Abstract:

Efforts were directed toward improved understanding of the slow potential SP of the brain. This electrically recordable dynamic differs from the conventional EEG in being nonrhythmic and of durations from 1 to many fold longer than the longest enduring components of the EEG. It is best elicited by use of motivating conditioned stimuli and by signals conditioning stimuli related to them in the learning process. A study was made of the relation of multiple firing potentials of neurons to the SP as both are related to temporal fixed interval conditioning controlled by medial forebrain bundle MFB electrical reward in the rat. A correlation was observed of the pacing of the level of expectancy in the trained subject with the SP, which, in this context, has been termed the Anticipatory Potential Gradient or APG.
